Cite as Mich. Admin. Code R 408.10729
Rule 729. (1) A cone belt and pulley shall be equipped with a belt shifter so
constructed as to adequately guard the nip-point of the belt and pulley. If the frame of
the belt shifter does not adequately guard the nip-point of the belt and pulley, the nip-
point shall be further protected by means of a guard which extends at least to the top of
the largest step of the cone.
(2) If the belt is of the endless type or laced with rawhide laces, and a belt shifter is
not desired, the belt will be considered guarded if the nip-point of the belt and pulley
is protected by a nip-point guard which extends at least to the top of the largest step of
the cone, and formed to show the contour of the cone in order to give the nip-point of
the belt and pulley the maximum protection.
(3) If the cone is located less than 3 feet from the floor or working platform, the
cone pulley and belt shall be guarded to a height of 3 feet regardless of whether the
belt is endless or laced with rawhide.
